Silicon Dioxide And Tricalcium Phosphate

Silicon dioxide and tricalcium phosphate are two separate ingredients often combined. Silicon dioxide, also known as silica, is a compound of silicon and oxygen found naturally in sand and quartz. Tricalcium phosphate is a calcium salt of phosphoric acid, often derived from animal bones or synthesized.

This combination is typically used as an anti-caking agent. It helps prevent powdered ingredients, such as spices or drink mixes, from clumping together. You'll often find it in seasoning blends, powdered drink mixes, and some baked goods.

Both silicon dioxide and tricalcium phosphate are generally recognized as safe (GRAS) by the FDA for use as anti-caking agents. They are indigestible and pass through the body. Regulatory bodies like JECFA and EFSA have evaluated these substances and found them safe for consumption at typical levels. There is no significant scientific controversy regarding their safety at the levels used in food.
